  • Sled dogs carry Astrobiologyto dizzying heights

    1999April 6, 2011

    NASA/Marshall's "Life on the Edge" program began in earnest last month when a dog sled team delivered 50 lb. of yeast and other microbes to a 13,000 ft summit in California's White Mountains.

  • Galileo buzzes Europa

    1999April 6, 2011

    The Galileo spacecraft executed a close flyby of Jupiter's moon Europa this weekend. Recent images strengthen the evidence for a liquid ocean beneath Europa's frozen crust and reveal new surface features in 3D.

  • Planets in a Bottle

    1999April 6, 2011

    NASA/Marshall's Life on the Edge program is barely a month old but it's already producing results in grade school classrooms. Students experimenting with "Planets in a Bottle" are learning about extremophiles and the prospects for life elsewhere in the solar system.

  • Clues to possible life on Europa may lie buried in Antarctic ice

    1998April 6, 2011

  • The shape of life: How does the computer "know" when it sees it?

    1998April 6, 2011

    NASA scientists, using artificial intelligence, are teaching computers to search for life-forms in extraterrestrial rocks, and to help researchers design new pharmaceuticals.

  • Surprises from Mercury

    2008April 6, 2011

    NASA's Messenger spacecraft has beamed back some surprising new data from the planet Mercury. Highlights include a weird crater nicknamed "the Spider," a planetary tail of hydrogen atoms, and measurements that show giant Caloris basin is even bigger than researchers thought.

  • MESSENGER Returns to Mercury

    2008April 6, 2011

    NASA's MESSENGER spacecraft is returning to Mercury. On Monday, Oct. 6, 2008, the probe will conduct the second of three planned flybys and photograph most of Mercury's remaining unseen surface.

  • Mercury Flyby Sets Stage for New Discoveries

    2008April 6, 2011

    Last week's historic flyby of Mercury by NASA's MESSENGER spacecraft gathered 500 megabytes of data and more than a thousand high-resolution photos covering nearly six million square miles of previously unseen terrain.

  • Mercury as Never Seen Before

    2008April 6, 2011

    NASA's MESSENGER spacecraft flew past Mercury on Oct. 6th capturing amazing new images of never-before-seen terrain.

  • New Discoveries at Mercury

    2008April 6, 2011

    Mercury's magnetic field is "alive." Volcanic vents ring the planet's giant Caloris basin while the planet itself is surrounded by a plasma nebula of unexpected complexity.
